Application filed September 7,1906- Scrial No. 333,588.

To HJ/ l/f/w//t 'lll/rl/ l/ (10H/cern,.-

Be it known that I, SAUNDER SAUNDER- -sON, a citizen of the UnitedStates, and a resiclosing while using the knife for its legitimate Ipurpose.

The invention consists of novel features and parts and combinations ofthe same, which will be more fully described hereinafter and thenpointed out in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews'.

Figure 1 is a side elevation of the improvement, showing the blade in anextended posil tion. Fig. 2 is a like view of the same, showing thesectional handle open for folding or closing' the blade. Fig. 3 is asectional plan view of the improvement on the line 3 3 of Fig. l. Fig. 4is a perspective view of the link for connecting the handle-sectionswith each other. Fig. 5 is a side elevation of the improvement in apartly-unlocked position; and Fig. 6 is a side elevation of theimprovement, showingI the blade concealed in the handle.

The blade A of the knife is adapted to be folded within thehandle-sections B and B or extended therefrom and locked in place forthe legitimate use of the knife. The handlesections B and BY arepivotally connected with each other at their outer ends by a link B2,and the said sections are made U shape in cross-section, so that whenthe sections are in a closed position they form a complete sheath forconcealing` the blade A when the knife is not in use. (See Fig. 6.) Thesection B carries at its forward free end a transverse pivot O, on whichthe heel A of the blade A is fulcrumed, and the said heel A is providedon opposite sides with notches A2 A3 for the free ends of thehandle-sections B and B to fit in, so as to hold the blade A locked whenin an extended position, as shown in Fig. l.

In order to hold the handle-sections B and B in a locked position whenthe blade A is in an extended position or in a folded position, thefollowing arrangement is made: The handle-sections B and B are providednear their free ends and at their abutting faces with interlockingtongues and grooves B3 B4, adapted to engage or disengage one with theother and to move the section B lengthwise on the other section B, itbeing understood that the link B2 permits such lengthwise movement ofthe sections B and B. (See Fig. 5;

In order to prevent the handle-sections B and B from openingaccidentally, a stirrup D is provided, having its side arms fulcrumed onthe pivot O andso as to permit of swinging the stirrup D over thehandle-sections B and B to straddle the same in a lengthwise direction.The stirrup D is so arranged that its middle portion D snugly vfits ontothe outer ends of the handle-sections B and B and the link B2 to preventthe sections B and B from becoming accidentally displaced while thestirrup D is in engagement with the handle-sections B and B, as shown inFigs. I and 3. The middle portion D of the stirrup D is provided with aknob or handle D2 for conveniently swinging the stirrup D into an openor a closed position, as indicated in the drawings. When the severalparts are in the position as shown in Figs. l and 3, the blade A isextended and is securely locked in position by the interlockedhandle-sections B and B, which in turn are locked in place by thestirrup D. Now when it is desired to fold the blade A within thehandle-sections B and B it is only necessary for the operator to rstswing the stirrup Dy into an open position, as shown in Figs. 2 and 5,and then to slide the section B outwardly on the sectidii B (see Fig. 5)to disengage the interlocking tongues and grooves B3 and B4 from eachother. When this has been done, the handle-section B can be swung intoan open position (see Fig. 2) to permit swinging theblade A within thehandle-section B, (see dotted lines in Fig. 2,) after which the sectionB is swung into a closed position, and its tongue and groove B4interlock with the tongue and groove B3, and then the stirrup D is swungback into a closed position, as shown in Fig. 6, to securely lock thehandlesections B and B against accidental opening;

IVO

TIO

The knife shown and described is convenient, simple, and durable inconstruction, and without the use of springs the knife-blade is heldsecurely inan extended position for the legitimate use of the knife, andthe knifeblade can also be concealed and locked in the handle wheneverthe knife is not in use.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A knife, comprising a handle made in sectionspivoted together to swing toward and from each other and to havelongitudinal movement relatively one to the other, means for locking thefree ends of the sections together, and a blade pivoted to the free endof one of the sections and engaged by the sections when said sectionsare in a closed position, to hold it extended.

2. A knife, comprising a blade, a handle made in sections having a linkconnection at one end, the said blade being pivoted to the free end 'ofone of the said handle-sections, and the latter are adapte-d tointerlock at their free ends, the latter engaging the heel of the bladeto lock the latter in an extended position.

3. A knife, comprising a blade, a handle made in sections hingedtogether, the said I blade being pivoted to the free end of one of l thesaid handle-sections, and the latter are adapted to interlock at theirfree ends, and a locking-stirrup fulcrumed on the pivot for the bladeand adapted to swing over the handle-sections to hold. the same againstopening.

4. A knife, comprising a blade, a handle i made in sections hingedtogether, the said blade being pivoted to the free end of one of thesaid handle-sections, and the latter are adapted to interlock at theirfree ends, and a l locking-stirrup fulcrumed on the pivot for the bladeand adapted to swing over the handle-sections to hold the same against Ivthe said handle-sections, and the latter are adapted to interlock attheir free ends, and a locking-stirrup fnlcrumed on the pivot for theblade and adapted to swing over the handle-sections to hold the sameagainstopening, the middle portieri fitting the hinged ends of the saidhandle-sections, one of theV latter having a shoulder for the saidmiddle portion to abut against.

6. A knife, comprising a pivoted blade having' notches at its heel, ahandle made in sections connected with each other by a link, the saidblade-heel being pivoted on the free end of one of the saidhandle-sections, the said handle-sections being adapted to engage thesaid notches and the said handle-sections being provided at their freeends with interlocking grooves and tongues.

7 A knife, comprising a pivoted blade having notches at its heel, ahandle made in sections connected with each other by a link, the saidblade-heel being pivoted on the free end of one of the saidhandle-sections, the said handle-sections being adapted to engage thesaid notches, and the said handle-sections being provided at their freeends with interlocking grooves and tongues, and a locking-stirrup havingits side arms fulcrumed on the blade-pivot and adapted to straddle thehandle-sections, the middle portion of the stirrup fitting the ends ofthe said handlesections adjacent to the link.

`ln testimony whereof I have signed my l name to this speciiication inthe presence of two subscribing witnesses.
